    本文介绍了使用CAD/CAM伸缩杆覆盖义齿修复口腔修复口腔癌患者(n=3)的结果,严重面部创伤(n=2),或各种综合征(n=1),都患有严重的组织缺陷,需要复杂而全面的口腔康复。目的是评估植入物保留的假体结构的耐久性和功能,确保简单的口腔卫生和最大限度地减少专门的后续需求。这项研究的数据来自赫尔辛基大学医院的回顾性队列。假体重建包括亚特兰蒂斯2in1和Createch可移动伸缩系统。因此,放置40个植入物(每个患者4至7个),上颌骨有假体结构(n=4例),在下颌骨(n=1),和两个钳口(n=1)。两名患者没有出现并发症,两名患者的丙烯酸树脂部分断裂,一名患者经历了钢筋结构的松动。所有与假体结构相关的并发症均得到成功治疗,没有一个植入物丢失。随访时间7~126个月。这种康复被证明是复杂口腔疾病患者的有效解决方案,促进功能恢复和易于维护。这些发现强调了在组织缺陷的情况下个性化治疗方法的重要性。
    This article presents the outcomes of prosthetic oral rehabilitation using CAD/CAM telescopic bar overdentures in patients with oral cancer (n = 3), severe facial trauma (n = 2), or various syndromes (n = 1), all suffering from severe tissue deficits and requiring complex and comprehensive oral rehabilitation. The aim was to assess the durability and functionality of implant-retained prosthetic structures, ensuring easy oral hygiene and minimizing specialized follow-up needs. The data for this study were sourced from a retrospective cohort at Helsinki University Hospital. The prosthetic reconstruction encompassed the Atlantis 2in1 and the Createch removable telescopic systems. Thus, 40 implants were placed (4 to 7 per patient), with prosthetic structures in the maxilla (n = 4 patients), in the mandible (n = 1), and in both jaws (n = 1). Two patients experienced no complications, two patients had part of the acrylic resin break, and one patient experienced loosening of the bar structure. All complications associated with prosthetic structures were successfully managed, and none of the implants were lost. The follow-up time ranged from 7 to 126 months. This rehabilitation is proved to be an effective solution for patients with complex oral conditions, facilitating both functional restoration and ease of maintenance. These findings underscore the importance of individualized treatment approaches in cases of tissue deficits.

    该患者系列报告了在常规修复和固定修复治疗中出现严重失败的唇腭裂患者(n=9,年龄27至76岁)的CAD/CAM假体重建的结果。该方案的目的是为单侧/双侧唇腭裂(UCLP/BCLP)患者建立功能性和患者友好的假体结构,同时最大程度地减少对left裂单元进行专业随访的需求。研究数据来自赫尔辛基大学医院的回顾性队列。假体重建是通过Atlantis2in1系统或Createch可移动望远镜结构使用CAD/CAM杆结构进行的,由四到八个上颌牙种植体支持。在九个病人中,七人没有并发症。由于原始框架的设计错误,16个月后发生了一个假体骨折,一名患者在牙科固定装置中出现骨整合失败(特别是,该患者的八个上颌植入物中的一个)。总的来说,成功放置了56个植入物。由于牙周和重建问题,老年唇腭裂患者的上颌牙列通常会带来挑战。植入物支持的CAD/CAM杆与可移动的望远镜超结构提供了一个易于维护和功能的解决方案,牙科康复。
    This patient series reports the outcomes of CAD/CAM prosthetic reconstructions in patients with cleft lip and palate (n = 9, aged 27 to 76) who have experienced significant failure with conventional restorative and fixed prosthodontic treatments. The objective of the protocol is to establish a functional and patient-friendly prosthetic structure for individuals with unilateral/bilateral cleft lip and palate (UCLP/BCLP) while minimising the requirement for specialised follow-up care in the cleft unit. The study data were obtained from a retrospective cohort at Helsinki University Hospital. Prosthetic reconstructions were performed using CAD/CAM bar structures by the Atlantis 2in1 system or Createch removable telescope structures, supported by four to eight maxillary dental implants. Out of the nine patients, seven experienced no complications. One prosthesis fracture occurred after 16 months due to a design error in the original framework, and one patient experienced failure of osseointegration in a dental fixture (specifically, one fixture out of the eight maxillary implants in this patient). In total, 56 implants were successfully placed. The maxillary dentition of elderly patients with cleft lip and palate often poses challenges due to periodontal and reconstructive issues. An implant-supported CAD/CAM bar with a removable telescope suprastructure offers an easily maintained and functional solution for dental rehabilitation.

    Lurbinectedin是致癌转录的选择性抑制剂美国食品和药物管理局(FDA)批准用于复发性小细胞肺癌(SCLC)患者的单一疗法,每3周3.2mg/m2(q3wk)。ATLANTIS是SCLC的3期研究,使用lurbinectedin2.0mg/m2加多柔比星40mg/m2q3wk与医生的选择,以总生存期(OS)为主要终点,以客观缓解率(ORR)为次要终点。这项工作旨在剖析lurbinectedin和多柔比星对SCLC抗肿瘤作用的贡献,并预测3.2mg/m2的单一药物lurbinectedin在ATLANTIS中的疗效,以与对照臂进行头对头比较。
    数据集包括387例复发性SCLC患者的暴露和疗效数据(ATLANTIS,n=288;研究B-005,n=99)。使用ATLANTIS对照组的患者(n=289)进行比较。使用浓度-时间曲线下的未结合血浆lurbinectedin面积(AUCu)和浓度-时间曲线下的总血浆阿霉素面积(AUCDOX)作为暴露指标。进行单变量和多变量分析以确定OS和ORR的最佳预测因子和预测模型。OS基线危害最好通过对数Logistic分布来描述,无化疗间隔(CTFI),乳酸脱氢酶,白蛋白,脑转移瘤,中性粒细胞/淋巴细胞比率,AUCu,AUCu和AUCDOX之间的相互作用作为预测因子。AUCu对ORR的影响最适合乙状最大反应(Emax)逻辑模型,其中Emax依赖于CTFI。
    与预测的3.2mg/m2lurbinectedin的头对头比较在ATLANTIS中产生了积极的结果,OS为0.54(0.41,0.72)的危险比(95%预测间隔[95%PI]),ORR为0.35(0.25,0.5)的比值比(95%PI)。
    这些结果支持lurbinectedin单药治疗复发性小细胞肺癌优于其他批准的治疗。
    UNASSIGNED: Lurbinectedin is a selective inhibitor of oncogenic transcription U.S. Food and Drug Administration (FDA)-approved for patients with relapsed small cell lung cancer (SCLC) as monotherapy at 3.2 mg/m2 every 3 weeks (q3wk). ATLANTIS was a phase 3 study in SCLC with lurbinectedin 2.0 mg/m2 plus doxorubicin 40 mg/m2 q3wk vs physician\'s choice, with overall survival (OS) as the primary endpoint and objective response rate (ORR) as the secondary endpoint. This work aimed to dissect the contribution of lurbinectedin and doxorubicin to antitumor effects in SCLC, and to predict the efficacy of single-agent lurbinectedin at 3.2 mg/m2 in ATLANTIS to allow for a head-to-head comparison with the control arm.
    UNASSIGNED: The dataset included exposure and efficacy data from 387 patients with relapsed SCLC (ATLANTIS, n=288; study B-005, n=99). Patients in the ATLANTIS control arm (n=289) were used for comparison. Unbound plasma lurbinectedin area under the concentration-time curve (AUCu) and total plasma doxorubicin area under the concentration-time curve (AUCDOX) were used as exposure metrics. Univariate and multivariate analyses were conducted to determine the best predictors and predictive model for OS and ORR. OS baseline hazard was best described by a log-logistic distribution, with chemotherapy-free interval (CTFI), lactate dehydrogenase, albumin, brain metastases, neutrophils/lymphocytes ratio, AUCu, and the interaction between AUCu and AUCDOX as predictors. Effect of AUCu on ORR best fitted to a sigmoid-maximal response (Emax) logistic model, where Emax was dependent on CTFI.
    UNASSIGNED: Head-to-head comparisons with predicted 3.2 mg/m2 lurbinectedin resulted in a positive outcome in ATLANTIS, with hazard ratio (95% prediction intervals [95% PI]) for OS of 0.54 (0.41, 0.72), and odds ratio (95% PI) for ORR of 0.35 (0.25, 0.5).
    UNASSIGNED: These results support the superiority of lurbinectedin monotherapy for relapsed SCLC over other approved therapies.

    现场研究表明,在受深水地平线(DWH)溢油影响的地区,底栖大型动物和小型动物的丰度随沉积物油浓度的增加而增加。底栖无脊椎动物生物量相对于岩性烃浓度显示出圆顶状关系,表明在低至中等的油浓度下对生物量有积极影响,而在高浓度下则有负面影响。如果这是由于底栖食物网的富集,然后,这增加了在大空间区域上出现的食物网响应的图像,由于DWH,丰度增加和减少。在模拟影响和恢复具有经济价值的物种时,我们将不得不考虑超出初始脉冲干扰的长期多物种影响。墨西哥湾的亚特兰蒂斯生态系统模型用于模拟三种机制,这些机制可以解释观察到的无脊椎动物群落变化。情景1是由于密西西比河水转移到Barataria湾(DWH溢油期间采取的缓解措施)引起的养分负荷,导致地表初级生产力受到刺激。情景2是由于海洋油雪沉积和絮凝物积聚(MOSSFA)产生的碎屑负荷,发生了底栖动物的富集。情景3是捕食者的减少和/或避开油区导致底栖无脊椎动物的捕食死亡率释放。方案2(MOSSFA)刺激了碎屑驱动的食物网,尽管有实际的油毒性,但最有可能导致无脊椎动物生物量的净增加。情景3(捕食者释放)似乎可能导致底栖无脊椎动物的变化。情景1(营养负荷)对底栖动物影响不大,表明底栖食物网与当地中上层生产来源脱钩。
    Field studies showed that benthic macrofauna and meiofauna abundances increased with sediment oil concentration in areas affected by the Deepwater Horizon (DWH) oil spill. Benthic invertebrate biomass shows a dome-shaped relationship with respect to petrogenic hydrocarbon concentrations suggesting a positive effect on biomass at low-to-medium oil concentrations and a negative effect at high concentrations. If this is due to enrichment of the benthic food web, then this adds to an emerging picture of a food web response over a large spatial area with both abundance increases and decreases as a result of DWH. We would be obliged to consider long term multispecies effects beyond the initial pulse disturbance in modeling impacts and recovery of economically valuable species. An Atlantis ecosystem model of the Gulf of Mexico is used to simulate three mechanisms that could explain observed changes in the invertebrate community. Scenario 1 is that stimulation of surface primary productivity occurred as a result of nutrient loading caused by diversion of Mississippi River water into Barataria Bay (a mitigation action taken during the DWH oil spill). Scenario 2 is that enrichment of the benthos occurred due to detrital loading from marine oil snow sedimentation and flocculent accumulation (MOSSFA). Scenario 3 is that predator declines and/or avoidance of oiled areas caused a release of predation mortality on benthic invertebrates. Scenario 2 (MOSSFA) stimulated the detritus-driven food web and was best able to cause a net increase in invertebrate biomass despite a realistic amount of oil toxicity. Scenario 3 (predator release) plausibly could have contributed to changes in benthic invertebrates. Scenario 1 (nutrient loading) had little impact on the benthos suggesting the benthic food web is decoupled from local pelagic production sources.

    生态系统模型需要初始条件的规范,这些初始条件具有一定程度的不确定性。重要的是在呈现模型结果时考虑到不确定性,因为它降低了错误或无代表性结果的风险。至关重要的是,模型结果被呈现为可能的包络,而不是只呈现一个实例。我们扰动了ChathamRiseAtlantis模型的初始条件,并通过比较许多初始条件扰动产生的模型输出,分析了这种不确定性对模型动力学的影响。在物种组层面,我们发现一些物种组比其他物种更敏感,营养水平较低的物种群通常对初始条件的扰动更敏感。我们建议通过评估生态系统指标在受干扰的初始条件下响应捕捞压力的一致性来测试强大的系统动力学。在使用复杂的端到端生态系统模型探索的任何一组场景中,我们建议将相关的不确定性分析纳入初始条件的扰动。
    Ecosystem models require the specification of initial conditions, and these initial conditions have some level of uncertainty. It is important to allow for uncertainty when presenting model results, because it reduces the risk of errant or non-representative results. It is crucial that model results are presented as an envelope of what is likely, rather than presenting only one instance. We perturbed the initial conditions of the Chatham Rise Atlantis model and analysed the effect of this uncertainty on the model\'s dynamics by comparing the model outputs resulting from many initial condition perturbations. At the species group level, we found some species groups were more sensitive than others, with lower trophic level species groups generally more sensitive to perturbations of the initial conditions. We recommend testing for robust system dynamics by assessing the consistency of ecosystem indicators in response to fishing pressure under perturbed initial conditions. In any set of scenarios explored using complex end-to-end ecosystem models, we recommend that associated uncertainty analysis be included with perturbations of the initial conditions.

    最近,我们报道了在人类胰腺中存在不同的细胞簇,称为腺泡样细胞簇,这些细胞簇与具有薄间质周围(ATLANTIS)的朗格汉斯胰岛接触。人类的形态学研究表明,在共同的基底膜封闭的微环境中发现了ATLANTIS和胰岛细胞簇。ATLANTIS将含有再生基因蛋白(REGIα)的囊泡释放到胰岛细胞簇。我们检查了1)纯合RegI(人REGIα的小鼠同源物)缺陷(RegI-/-)和野生型小鼠中是否存在ATLANTIS,和2)在RegI-/-和野生型小鼠中脑心肌炎(EMC)病毒(D变体)感染后,ATLANTIS在β细胞簇再生中的可能作用。在野生型和RegI-/-小鼠中都发现了ATLANTIS。在这两组中,在EMC病毒感染后第5天,平均血糖短暂升高至大于14.0mmol/L,并在第12天恢复至基线.EMC病毒感染后12天,与野生型小鼠相比,在RegI-/-小鼠的胰岛β细胞中观察到较低的BrdU标记指数。RegI-/-小鼠中EMC病毒感染后12天的β细胞体积与野生型小鼠没有差异。这些结果表明RegI,从ATLANTIS释放到胰岛β细胞簇,在EMC病毒诱导的糖尿病的β细胞再生中起着至关重要的作用。还提出了在EMC病毒破坏后的β细胞恢复中存在除RegI介导的机制以外的机制。
    Recently, we reported the presence of distinct cell clusters named acinar-like cell clusters touching Langerhans islets with thin interstitial surrounding (ATLANTIS) in human pancreas. A morphological study in humans demonstrated that ATLANTIS and islet cell clusters are found together in the microenvironment enclosed by a common basement membrane, and ATLANTIS releases vesicles containing Regenerating gene protein (REG Iα) to islet cell clusters. We examined 1) the presence or absence of ATLANTIS in homozygous Reg I (mouse homologue of human REG Iα) deficient (Reg I-/-) and wild-type mice, and 2) the possible role of ATLANTIS in the regeneration of beta cell clusters after encephalomyocarditis (EMC) virus (D-variant) infection in Reg I-/- and wild-type mice. ATLANTIS was found in both wild-type and Reg I-/- mice. In both groups, mean blood glucose increased transiently to greater than 14.0 mmol/L at 5 days after EMC virus infection and recovered to baseline at 12 days. At 12 days after EMC virus infection, lower BrdU labeling indices were observed in islet beta cells of Reg I-/- mice compared to wild-type mice. Beta cell volume 12 days after EMC virus infection in Reg I-/- mice did not differ from that of wild-type mice. These results suggest that Reg I, which is released from ATLANTIS to islet beta cell clusters, has a crucial role in beta cell regeneration in EMC virus-induced diabetes. The presence of mechanism(s) other than that mediated by Reg I in beta cell restoration after destruction by EMC virus was also suggested.
